Photon Torpedo

I take exception to the theory put forth by W4FD and W4ATE (Juiy, 1981, p. 52) that photons of light constitute the medium through which radio waves propagate. The theory sounds somewhat plausible but has one major deficiency. Namely, if radio waves ' need some sort of medium to travel in (such as an ocean of light photons), then what sori ot medium exists for the propagation of light ,lwavestr Perhaps, the authors would suggest that since radio waves travel through light waves, then light...

Zhzz Or Any Common Npn Switch

For many years t have used my ohmmeter to test diodes The usual technique was to set the meter on R x 10, fumble with the test leads to get a low reading OK in the forward direction , reset the meter to R x 100 or R X 1000, re-fumble to reverse the diode, and check for a high reading OK in the reverse direction . Usually, around the second fumble I would lose track as to whether t actually reversed the diode and would have to fumble a few more times to recheck. Recently, I purchased a bag of...
